The Gibson neck. I don't care how many comparable imports you put next to a Gibson (even the lowest end Gibson like the melody maker), any of us can blindfold ourselves and tell the difference just by running our hands around the neck and across the fretboard.
There is no "Gibson neck." There are over 100 models of the Les Paul alone and there's a wide variety of "Gibson necks" out there. I have a bunch of them. I can tell you without question that my '49 ES-175 has a different neck from my '67 ES-335s or the L5S or the L6S (1 9/16ths" wide at the nut, like a lot of the same-era SGs). I can guarantee you that I can hand you 10 different Gibsons from my stock alone and that those 10 will all have different size necks. And who are "any of us?"
BTW -- I went to school with John Sevier from Sevierville, in Sevier County, TN (around the corner from you) whose great great somebody or other was the first governor of TN and whose grandmother owned (at the time) Bluebell/Wrangler jeans. Seems to me I remember a nearby Maryville...
